Understanding the Shared Operation of Commuter Rail Transit and Freight Railroads

Abstract

Seeking a thorough understanding of shared operation between commuter rail transit and freight railroads, a nationwide survey was conducted of transit and rail freight interaction. This survey contacted and received responses from all 21 commuter rail services in North America. In addition to a general understanding of the shared-use practices, this paper presents the key factors that contribute or impede successful shared-use operations between commuter rail and freight railroads by examining detailed operation arrangements, shared asset management, dispatching priorities, accident histories, and insurance and liability issues. A few critical issues directly related to the success of future shared operations are highlighted for the reference of new-start systems and those who are seeking knowledge in the arena of shared-use operations.
